Abstract: ABSTRACT:        An improved locking tab for horizontal components of hook-in type shelving, the locking tab being integral with the horizontal components and bent into the upper part of one of the slots of vertical shelf-supporting posts, this locking tab having in its preferred form an upper surface that is slanted backwards so that when the tab is moved to the locked position, this surface is perpendicular to the centerline of the post, thus preventing the locking tab from being bent back by shaking of the shelving; and a secondary tab with a shoulder surface abutting the post when the tab is bent into the locked position and a surface displaced from the post such that the end of a screwdriver can be placed between the latter surface and the post and twisted to bend the locking tab back into its original position, thus making it easy to dis-assemble the shelving.

Abstract: METHOD OF MAKING RECONSTRUCTED TOBACCO, AND RECONSTITUTED TOBACCO          MADE THEREBY Abstract of the Disclosure Reconstituted tobacco is made from the whole tobacco plant by first separating the woody stalk portion and leaf portion of the plant.  The stalk portion is refined, or beaten, apart from the leaf portion to reduce it to pieces which can bond to form a paper-like sheet.  The leaf portion is refined to a lesser extent to similarly reduce it.  The stalk and leaf portions are combined and formed into a paper-like sheet by a conventional papermaking technique.  At least the leaf portion is extracted before refining to separate it into a soluble extract and a fibrous residue, the extract later being introduced into the paper-like sheet.  The stalk alone may be refined for a period of time after which the unrefined leaf portion is added to it and the combined stalk and leaf portion  then refined together.  A part of the stalk portion may be discarded, and conventional non-tobacco papermaking fiber added to the stalk and leaf portions prior to making the paper-like sheet.

Abstract: ABSTRACT IN A HEATING DEVICE IT IS KNOWN TO HAVE A HEATING ELEMENT SUPPLYING HEAT TO BE USED ON ONE SIDE OF THE HEATING ELEMENT.  IN THIS INVENTION A PARABOLIC HEAT REFLECTOR IS PROVIDED WITH A HEAT COLLECTOR IN THE FOCUS OF THE REFLECTOR AND THE HEAT COLLECTOR ITSELF IS CONNECTED WITH THE HEATING ELEMENT BY A HEAT CONDUCTOR. THE REFLECTOR REDUCES THE HEAT LOSSES RESULTING OF RADIATION AND THE HEAT COLLECTOR DELIVERS HEAT TO THE HEATING ELEMENT WHICH RESULTS IN A BIGGER DIFFERENCE BETWEEN THE TEMPERATURES OF THE SUBSTANCE TO BE HEATED AND THE HEATING ELEMENT ITSELF. BECAUSE OF THE HEAT BEING CONDUCTED AWAY FROM THE HEAT COLLECTOR TO THE HEATING ELEMENT THE COLLECTOR ITSELF IS COOLED WHICH REDUCES THE RADIATION OF HEAT FROM THE COLLECTOR TO THE REFLECTOR. TO REDUCE HEAT LOSSES BECAUSE OF HEAT CONDUCTION THROUGH THE REFLECTOR THE REFLECTOR MAY BE INSULATED ON ITS OUTSIDE.

Abstract: COAL LIQUEFACTION PROCESS WITH A PLURALITY OF FEED COALS             ABSTRACT OF THE DISCLOSURE           In a coal liquefaction process including recycle to the liquefaction zone of a product slurry (14) containing mineral residue, the minimum slurry recycle rate is determined by a pumpability constraint on the solids level of the slurry contained in the feed coal mixing vessel (6).  If the solids level in the feed coal mixing vessel (6) rises above the constraint level, the slurry recycle rate must increase.  For coals which generate a high mineral residue content, adequate dilution of the slurry in the feed coal mixing vessel requires the slurry recycle rate to rise to an economically impracticable level.  To avoid a high recycle rate the catalytic advantage of recycle solids is increased by reducing the median diameter of the particles in the recycle slurry stream by passing a portion of the product slurry through a hydroclone (60) to produce a second recycle slurry comprising hydroclone overflow (61).  The process employs a plurality of feed coals (1, 112), one of which upon dissolution generates smaller and more catalytically active particles of mineral residue than the other.  The hydroclone overflow stream (61) selec-tively concentrates in the recycle slurry the smaller mineral residue particles generated from said feed coal.

Abstract: Abstract Spinning process Fibres are produced by centrifugal spinning a solution of thermosetting aldehyde resin, e.g. an aqueous UF resin solution, and drying the fibres by contact with a stream of hot, dry, air flowing downwardly from above the spinning cup. To avoid premature drying of the resin solution and fibres, a stream of cold, humid, air is fed to the spinning cup, from whence it is thrown, by rotation of the cup, as an outwardly directed stream having the fibres entrained therein.  This out-wardly directed stream of cold, humid, air is deflected downwards, e.g. by the hot, air stream or by a subsidiary cold air stream, to avoid the formation of a vortex into which the fibres might become entangled.

Abstract: ABSTRACT Several types of transmission filters are disclosed having specified transmittance functions to eliminate strobing in scanning an image through an aperture onto a photoreceptor.  A general requirement or condition on photoreceptor irradiance profiles has been found to minimize strobing.  Photoreceptor irra-diance profiles are generally the product of the time irradiance function of the periodically energized illumi-nating lamp and the spatial irradiance profile across the aperture near the photoreceptor. It has been found that strobing is eliminated if the Fourier transform of the spatial irradiance profile is zero, evaluated at the fundamental frequency of the illuminating lamp and at those multiples of the fundamental frequency at which the lamp has power.  A transmission filter with predetermined transmittance characteristics therefore, can be disposed in the image path near the aperture to provide a spatial irradiance profile having a zero Fourier transform at the required spatial frequencies.
